WILLIAM D. LORD, OF HARTFORD, CONNECTICUT.

Covina DEVICE.

Application filed April 18, 1924. Serial No. 707,520.

This invention relates to cover devices and particularly to a cover structure appropriate for application to tobacco pipes.

The object of the invention is the provision of a simple, practical, durable device which may be inexpensively manufactured, readily adapted to tit different styles of pipe bowls and so constructed as to permit of its being quickly applied to or removed from a pipe.

In the drawings,-

Figure 1, is a side view of a pipe with a part of the bowl, a cover therefor, and a. support for the cover shown in section.

Figure 2, is a top view oit the pipe, cover and cover support shown in Fig. 1.

Figure 3, is a sectional view on line 3 3 of Fig. l.

Figure Ll, is a perspective detail view cfa cover having a pintle integral therewith.

Figure 5, is a perspective detail view of a cover support hereinafter more fully described, and

Figure 6, is a sectional view of a modified form of cover provided with bent lugs to engage a pintle non-integral therewith.

The device illustrated as embodying my invention comprises a pipe bowl cover and a. support therefor. The support is in the nature of a spring clip adapted to be easily engaged or disengaged from a pipe bowl and it is provided with a bearing to pivotally and resiliently engage a' pintle associated with the cover so that the latter may be swung open or closed and maintained by spring pressure in either position.

The cover 2, comprises a dish stamped as shown with a slightly beaded edge or other wise to make it of appropriate appearance and of-.a form to snugly fit the bowlof a pipe as 3, the disk being made of suitable material to insure strength and durability. The cover is perforated with ventv holes 4.-, and an opening 5, the latter extending through a projecting part 6, of the rim 7, to provide clearance for a supporting member and to form a iiattened bar or pintle 8, supported at both ends, and adapted to be engaged by the support in a manner` that will hereinafter more fully appear. The support (see Fig. 5) may be bent into form from a fiat strip of metal. This strip at one end is formed into the receptacle engaging clip 9, then folded upon itself at 10, and extended in an arm 1l, with a surface thereof adjacent a surface 0f the intermediate section l2, of

the clip. One of these surfaces is provided with a depression which may be formed by bending the arm 1l, as at 13, to form with the other surface an opening or bearing for the reception of pintle 8, of cover 2. Due to resiliency of the material of which the support is made, the clip portion is adapted to iirmly engage the rim of a receptacle as that of a pipe bowl, and also by virtue of resiliency in arm 1l, the pintle of the cover may be readily sprung into opening 13, which is in effect a split bearing, opposed walls of which bear upon the pintle with yielding pressure. The pintle 8, is iiattened in transverse section and the spring pressure between opposed sides of its bearing tends in either open or closed position of the cover to force a respective fiat side of the pintle toward the adjacent flat side of the bearing.

This force acting against one side of the pintle holds the cover firmly upon its' seat. When acting upon the other side of the pintle the cover will be moved to open position and maintained at a deiinite angle, with a flat side of the pintle against the fiat side of the bearing. This angle which the cover assumes in its open position is determined by the angular relation between the flattened pintle and the cover, and the desired angle may be secured by suitably bending the lug or projection 6, of which the pintle is formed, see Fig. 4. In order to effect movenient of the cover to either the closed or open position it is turned slightly beyond an l,

intermediate position or that in which the pintle is on a dead center with relation te the pressure exerted between the sides of the bearing by which pressure the cover is rotated and held in its normal positions.

At its free edge the cover may be slightly dented as shown to Vform a finger nail hold to facilitate moving it from its closed position.

Figure 6, illustrates a form of cover somewhat modified in that the pintle l?, is a separate piece secured by lugs 18, bent into engagement therewith.

lVhile my invention is specifically illustrated and described as embodied in a tobacco pipe appartenance it will be apparent that it is applicable in cover structures for Various receptacles without departure from the scope of invention defined by the appended claim.

Having thus described my invention, what I claim is,'--v

In combination, a cover perforated to of the other zt bearing opening which is separable to receive the flattened pint-le of 10 the cover and cooperative therewith both to effect and prevent movement of the cover by Virtue of the resiliency of the arm.

In testimony whereof I aiiX my signature.
